Make slime yourself: the best recipes

Whether it's Fluffy Slime, Galaxy Slime or Illuminated Slime: we've been looking for the best recipes. Have fun making your own slime!

Children love play slime – but unfortunately the slimy mass is not always completely harmless. As early as 1995, the Federal Institute for Risk Assessment issued a warning against the so-called slime. Unfortunately, that didn’t change much! To this day, products continue to perform poorly in tests – most recently in October 2018. Scientists found that many slime secrete too much Boric acid. Boron is added to the slime to give it its typical consistency. However, toys in the EU are not allowed to give off more than 300 milligrams of boron – three out of five ready-made slimes examined exceeded this limit by more than twice! In higher concentrations, boric acid can have harmful effects on fertility and unborn life. If larger amounts are absorbed by the body, for example swallowed, this can lead to diarrhea, vomiting and cramps.

So should children be banned from playing with slime completely? no way! Because there is a great alternative. And that is:  make your own slime ! Best of all, your kids will love throwing the ingredients together and kneading until the mixture is really nice and slimy. We’ll show you lots of simple recipes for lots of goo fun!

1. Make non-toxic slime yourself with marshmallows

Probably the most ingenious recipe for play slime consists of marshmallows, flour and food coloring. Since these ingredients are all food, it’s not even a problem if your kids snack on them. The edible slime even tastes really delicious thanks to the many marshmallows.

You need: 

  • 18 marshmallows, about 180 grams
  • about six tablespoons of flour
  • Food coloring
That’s how it’s done: 
  1. Heat the marshmallows in the microwave for about 30 seconds. Repeat until liquid. In between, mash it up with a fork. Alternatively, you can heat them in the oven at 100 degrees for 20 minutes.
  2. If you don’t want the slime to stay white, you can color it up with food coloring.
  3. Then gradually add the flour to the mass and knead until the slime has reached the desired consistency. It is best to dust your hands with flour beforehand, as the play slime is very sticky.

2. Metallic slime with glue

This magical glitter slime looks like molten metal.

You need: 

  • 2/3 cup clear glue
  • golden glitter dust
  • golden food coloring
  • 1 teaspoon Baking powder
  • 1 tsp contact lens solution

That’s how it’s done: 

  1. Pour the glue into a bowl, then add the glitter dust and gold paint.
  2. Now add the baking powder and mix everything together with the help of the spoon.
  3. Now slowly stir the contact lens solution under the glue. Once the slime separates from the bowl, knead it into a ball. If the mass is too sticky, simply add a little more contact lens solution.
  4. If you want your metallic slime to be even more sparkling, add some more glitter dust.
  5. Et voilà: The finished metal slime looks so cool.

Tip:  Of course you can also experiment with different colors or use silver instead of gold to make the slime look even more spacy.

3. Make slime yourself with detergent

Many homemade slimes are made with detergent and contact lens solution. No wonder, because these ingredients also contain boron or borax, which provides the slimy consistency. So we would like to point out that these slimes are not non-toxic either – however, only very little contact lens solution or detergent is used in the recipes. It is important that your children do not put the slime in their mouths or touch their faces with their fingers while playing. You should definitely wash your hands thoroughly after the goo-slime session – and you should do the same if you played with store-bought slimes, by the way.

You need:

  • 1 tube of liquid glue (water-soluble and solvent-free)
  • Liquid Detergent
  • Warm water or contact lens solution
  • if necessary, food coloring for coloring

That’s how it’s done: 

  1. Place the craft glue in a bowl. A 125 ml tube is enough for one slime. You can either use clear glue or white craft glue – depending on whether you want the slime to be transparent later or not.
  2. Now very slowly add a very small amount of detergent (approx. two milliliters) and stir with a wooden spoon. The more detergent that is added, the less viscous the slime will become. By the way, colored detergent colors the goo directly. Alternatively, you can also add food coloring.
  3. Finally, add a little warm water or a maximum of half a teaspoon of contact lens solution.
  4. Mix the ingredients together until the slime no longer sticks to your hands. Then it has the perfect consistency to play with.

4. No Glue Slime Recipe

Of course, many parents prefer to make non-toxic slime themselves. Although the glue in the above recipe is solvent-free, some moms and dads still find it too dangerous. And the detergent is not entirely harmless either. Luckily, there is another recipe for slime without glue besides marshmallow slime.

You need:

  • 2 cups cornstarch (from the bakery section of the supermarket)
  • approx. 350 ml hot water
  • possibly food coloring

That’s how it’s done: 

  1. Boil 250 ml of water and put in a bowl.
  2. If you want colored slime, you can now stir food coloring into the water.
  3. Pour the cornstarch into a second bowl.
  4. Slowly add the colored water while stirring constantly.
  5. The overall consistency of this slime is a bit more viscous than slime made with glue. If it’s too runny, add a little cornstarch. If it is too solid, it can be made more liquid with a few drops of water.

5. Fluffy slime made from shaving cream

This homemade slime is really something very special. Because of the shaving foam, it is not as sticky as the others, but wonderfully fluffy. However, it does not last as long as the others and therefore needs to be redone more often.

You need:

  • about two hands full of shaving cream
  • half a tube of glue (approx. 60 g)
  • contact lens solution
  • possibly food coloring

Here’s how: 

  1. First put the shaving cream in a bowl. As a rule of thumb, the more shaving cream, the more mucus. So don’t empty the whole can right away!
  2. Now slowly add the glue and mix well.
  3. Stir in some food coloring for colored fluffy slime.
  4. Finally, contact lens solution is added in small quantities. The super fluffy DIY slime is ready.

6. Make your own slime with soap

You need: 

  • Children’s shampoo or children’s shower gel (250 ml)
  • Colored crackling bath salts
  • 1-2 teaspoons flour

That’s how it’s done: 

  1. Pour about a quarter of the shampoo into a bowl.
  2. Then add the colored crackling bath salts.
  3. Gradually add a teaspoon or two, stirring well with a spoon.

The kids can rub the slime in the tub themselves or turn the tub into a slime paradise. Don’t worry: the color can be removed without leaving any residue – even from the hair.

7. Galaxy slime

Slimy goo is already very popular with the little ones – but their eyes light up a little more when glitter slime is made. To do this, the slime is simply made according to the instructions described above and then spiced up with glitter (from the craft store).

8. Rainbow Slime or Unicorn Slime

Superlative DIY: Make different slimes in different colors and then add glitter. Twist the individual slimes into strands and then braid them. These colorful rainbow slimes, also known as unicorn slimes, are really eye-catching!

9. Glow Slime

Your kids will also love this slime production: instead of food coloring, glow-in-the-dark color is mixed into the basic recipe. The slimes then glow in the dark.

10. Scary Slime

Especially popular on Halloween: Put small gummy worms, plastic spiders or bats in the goo. That feels really gross!
